"A scooter!" you announce. You are announcing this because you decided this is what you would create.
Imagine being at a maker's contest. Each person has to announce loudly what they'll create, then they have to create it.

But, a scooter has been created before. What is different about yours? The scooter you will create is specifically designed to keep zombies (ぞう) busy.
Imagine the scooter you created with a zombie on it. It's a perfect place for the zombie to get stuck and scooted off into nowhere.
